Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 5P and 4B. PP2 PP3_Strong BS2

The NM_002850.4(PTPRS):c.5129G>A(p.Arg1710His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000564 in 1,613,972 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1710C) has been classified as Uncertain significance.

Genes affected

PTPRS (HGNC:9681): (protein tyrosine phosphatase receptor type S) The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP contains an extracellular region, a single transmembrane segment and two tandem intracytoplasmic catalytic domains, and thus represents a receptor-type PTP. The extracellular region of this protein is composed of multiple Ig-like and fibronectin type III-like domains. Studies of the similar gene in mice suggested that this PTP may be involved in cell-cell interaction, primary axonogenesis, and axon guidance during embryogenesis. This PTP has been also implicated in the molecular control of adult nerve repair. Four alternatively spliced transcript variants, which encode distinct proteins, have been reported.

The c.5129G>A (p.R1710H) alteration is located in exon 33 (coding exon 32) of the PTPRS gene. This alteration results from a G to A substitution at nucleotide position 5129, causing the arginine (R) at amino acid position 1710 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
